Application filer; Segtemher 1.4 1911vv Be il'v known that I, Fem) A.PUINAM, a citizen of the Unified Stole" residing at. Melrose, county oflvlir lilleserg Sluts of Muss-w eliusetts, have inrei'aieil animprovement in PllIliLll'lQ lllflOllb105, of: which the followingdeseripl ion, in ('(Hllli ll'lfi'fl Willi the oer-our puuying uni-wingis a spwiiirutieu. like iburmr ters on the drawing representing; likeparts.

This invention ltlilbfi in printing nu1- chines which are adapter" inprint an im pression on leather, elolih ,or other similar sheetmui'eriul, null the olqrcls oi the inmution are to prorirle a novelprinting uuvifbine by which I'EIHI :(l impressions (an be mrnle withextreme rapidity and by which the printing surface can be applied to themuteriulto be printed with :1 high pressure. I

attain these objects by employing :1. rotary printing member carryingthe priming; surfnve and the device is constructed so that this rtnrymember is not only u printing member, bulz is also a feeding member sothat by. its rotation it operates both to feed the material to beprinted and apply the impression thereto.

I prefer to make the printing member with a plurality OiMljllStiIblGtype members, ezu'h having a plurality of printing CllflIlIC- tersthereon, so that by adjusting the yarious vtype members the character ofthe 'unpression may be vur ecli Ihese type members are shown, in theform of type disks and are carrier}, by the printing; member so as toturn about an axis extending transverse to the axis of roiaiion. Thearrangement is such that, the imerziizi've chumccers of the type diskstand substantially in the line of the periphery of the rotating memberso that as the member is rotated the ehaructersone after the other willbe brought into contact with the work and thus the impression isprogressively made.

I have illustrated herein one simple embodiment of my in veution whichis suflicient to ShOW the prim-hale thereof, but I Wish it understoodthat the constructional details may be varied in may WuyS WitbOUt deparing from the invention.

In the ill-ru ings, Figure 1 is an end \iew of n printing muehineembodying mv invention with a portion of the frame broken out; Fig. 2 isa vol-lion] section through the frame, said eeotio'u passing through theret-az v rinting uwmbirr on substantially the line rr' *s-=. Fig 1; Fig.3 is a perspective view of one of 2hr type disks; Fig. 4 shows :inimpleinouii whirl] may be used for adjusting ihe type disks se iuuztelThe rotary prim/i member is shown at 1 and may have any suitable shapeor construction. It is shmvn as mounted. on a shaft 2 which is suitablyjournaled in a bearing 3 susi'uined by a frame or base piece r. Theslmfi .2 rm be driven in any suitable way withoui departing from. thein'vew lion I have herein shown said shaft as boring: thereon :1, gearWheel 5 which is adapted to mesh with and. be driven by asuitnbiysustuint-1i driving gear (not shown), although it would bewithin my invention to apply a driving; pulley directly to the shaft.

The printing u'iember l'carries one or more printing or type members 6which curry type i hat. are adapted to be brought into the line of theperiphery of the member '1. These type members 6 may be constructed invarious ways without departing from the invention. I prefer, however, tomake them in the form of disks, as shown in Fig. 3, which are providedon their e riphery with separuted type 'or printing characters *1. Iwill also preferably make each disk 6 with a notch 8 between adjw centtype. These type disks 6 are mounted in a reeess 9 formed in theprinting member 1 and are sustained by a shaft or pin 10 which is seemedin the printing member and which extends transversely to the directionof the shaft Each type disk 6, therefore, is capable of adjustment aboutan axis transverse 20 the axis of rotation of the printing member. Withthis construction it will be seen that by turning the various type disks6 about the shaft 10 any printing character on each disk can be broughtinto the peripheral line of the printing member this being the printinggiq sition of the type.

The work or material to be printed is shown at 11 and it is placed onthe bed 4. As the printing member 1 rotates it acts to feed the work 11homes the bed 4 and at the same time the adjusted type 7 are broughtinto contact with the upper face of the work 11 and thus an impressionis madethereon. I prefer to em loy a presser or feed roll 12 to assistin fee ing the work across the bed. This roll is shown as jonmaledbeneath the bed 4 in yieldingly-sustsined bearings 13 first are movablevertically in suitable ways 14 and are acted upon by sprin 15 which tendnormally to hold the rol elevated. Steps 16 are provided which limittheupward movement of the roll and in its normal position said roll is.snfiiciently below the printing member 1 so that said member will rotatefreely without contacting with the roll. Whenever a piece of sheetmaterial 11 is fed into the space between the roll 12 and the )rintingmember 1, however said mo teria will be gripped between said member androll and will be fed thereby during which operation the impression willbe made as will be obvious.

I have provided a. constrnction whereby the material 11 can be placed onthe bed adjacent the roll 12 and will remain there until the printingmember has reached substantially the position shown in Fig. 1, at which.point the work 11 will he engaged by the printing member and will be fedforward thereby. Lhave shown the printing! member 1 as having a feedingprojection 1 thereon adiacent the type disc 6. This projection mayconveniently be made of rubber or any other friction material end is ofsuch a length that it will normally clear the roll 12, but when thepiece of material 11 to be printed is placed in the position shown saidprojection will engage said material as the proyee tion rotates in thedirection of the arrow 0 and will thus feed it forward.

It will be noted. that the type which make the impression are arrangedin a line along the periphery of the rotary member 1 so that these typewill be brought successively into engagement with the material ll. Thisis an advantage because the full pressure ot the springs 15 is appliedto each type in succession so that the effect is the some as \voilld becaused if ouch type made its impression separately. As 'a result it ispossible to apply a heavy pressure to the print 'mg type if desired ownthough the mark which is to lll' printed contains a large number ofseparate charm-tors. in fact tlu' numlNl of the separate china-odorsdoes not in any way :1 il'vct the prcssurc which is applied during, theprinting: operation.

A device such as above described could be used merely for embossingleather or other sheet material by the pressure of the against saidmaterial. If, however, a print ing impression is to be made the type,can be inked in any suitable way without departing from the invention. Ihave herein shown an inking roll 20 which is adapted to be engaged bythose type which are in printing position as the printing memberrevolves and which is journalcd in suitable bearings 21 carried by theink reservoir 22. Said roll 20 contacts with an ink-distributing roll 23which operates in the ink reservoir and distributes the ink to theinking roll 20. This ink reservoir may be conveniently sustaincd on asuitable bracket or stand 24: or may be supported in any otherappropriate we have shown in Fig. 4: a simple implement by which theindividual type disks can be readily adjusted to bring any ty e thereoninto printing position. This implement which is shown at 25 has the headportion 26 adapted to fit into the notches 8 so that by inserting theimplement into one of the exposed not-ches 8 of any of the disks, saiddisk can be turned about the shaft 10. The disks are normally held intheir operative position by holding pawls 27, one for each of the disks,said pnwls being pivoted to the printing member st 28. and each havingthe head portion :29 adapted to engage one of the notches 8. Each pawlyieldingly held in position by a. suitable spring 38. Each disk is shownas cut away on its periphery as at 31 to allow room for the holdingpawlsfl'i;

By using a rotary printing member it is possible to make the successiveimpressions with oxtrmne rapidity, and further it is possible to apply:1 high degree of pressure in making the impression from each type.

I have shown herein a simple embodiment of my invention which issullicient to illus trait-e the principle of it, but do not wish to belimited to the constructiomll details shown.
